CURTAIN-FASTENER.

Specification of Letters Patent.

Patented oet. 2e, 1909.

Application led August 13, 1908. Serial No. 448,370.

To all whom it may concern:

Be it known that we, GEORGE B. JOHN- soN and RALPH C. COTTON, citizens of the United States, residing at Pawnee City, in the county of Pawnee and State of Nebraska, have invented a new and useful Curtain- Fastener, of which the following is a specication.

This invention relates to curtain fasteners; and has for its object an improved fastener for securing curtains, such as are used on carriages, to the ordinary projecting buttons, and locking said fasteners to said buttons for preventing accidental disengage-V ment of the curtain. 1

With this object in view the invention consists of the novel construction, combination and arrangement of parts, hereinafter described and claimed and illustrated in the accompanying drawing, in which- Figure l is a perspective view of the fastener applied; Fig. 2 an enlarged front view of the fastener opened to receive a button; Fig. 8 an enlarged rear view of the button in closed position; Fig. 4 a cross sectional View of the fastener attached to a button; and Figs. 5, 6 and 7 are views of a modified form of the device.

Similar reference characters are used for the same parts in all the figures.

In the drawing, 1 indicates a thin flat circular plate provided with peripheral fingers 2 for attaching said plate to a curtain in the usual way, and having an outwardly turned lug 3 at its edge formed by cutting the plate and turning up the por tion between said cuts.

Diametrically opopsite the lug 3 near the edge of the plate 1 is a pin 4 forming the pivot for two semi-circular plates or locking dogs 5 and 6 having preferably the same radius as the circular plate 1. The straight edges of the two locking dogs are normally held in contact on a line passing through the center of the plate l, the pin 4 and the lug 3, by a bow-shaped spring 7 which is held assembled with the locking dogs by keepers 7b which engage its free ends, said springs bent around the axis of the fastener, a plurality of coils being made in the spring An elongated Opening 9 is made in the middle of the plate 1 of sufficient size and shape to permit a curtain fastening button A, such as are used on vehicles, to pass freely therethrough. A semicircular or other shaped notch 10 is made in the straight edgey of each dog 5 and 6 which, when thev dogs are in contact form an opening 1()a of less diameter than the head of the button A.

Constructed as above described and secured to the curtain B by means of ngers 2, a fastener is attached to a button A by pressing outwardly on the finger pieces 7a until the locking dogs 5 and 6 are separated sufficiently to permit the head of a button to pass between them when the fastener is assembled therewith. As soon as the fasteners are in place, the locking dogs 5 and 6 are released and immediately close below the heads of the buttons, securing the fasteners thereto and holding the curtain closed against accidental or unintentional separat-ion.

In the modified form of the device, illustrated in Figs. 5, 6 and 7 but one locking dog 11 is employed. This dog is pivoted on a pin 4, as in the preferred form on the outside of the plate 1a. The opening 9 in plate 1 is larger than in the preferred form of the fastener and lies wholly below the locking dog. A bow spring 7 having one end fastened to the plate 1 and the other to the dog 11 holds the latter in closed position with the depressed portion 12 on its straight edge in contact with the straight edge 13 of the plate 1. A central opening 14 corresponding to the opening 10 is formed by notching the plate 1 and the locking dog 11. In this type of fastener the button head is released and secured by swinging outwardly the single dog 11.

What is claimed is A curtain fastener comprising pivotally connected members provided with means to interlock With a button and with keepers, as our own, We have hereto affixed our sigand abowedfspring lying Whollly Withinthe natures in the presence of twouwitnesses.

perip ery o the members anc having its terminals passed through the keepers and 5 deflected to provide finger holds that operate in conjunction With the keepers to hold the Witnesses:

spring assembled with the members. s M. H. MARBLE,

In testimony that We vclaim the foregoing JOHN PATTISON.
